I like Google Drive and Google Docs. It’s a great tool that handles 99% of my business needs. At times you may need to have access to these docs on your phone. In those cases where editing is needed Google has added functionality. But it is not always a pleasant experience. In the cases where you need to do more than just change a few words in a document consider going to Quickoffice. Now that it’s free and Google owns it you can take great advantage of the better editing tools it provides.
For fast access with little or no changes stick with Google Drive. When it’s time to manipulate your files Quickoffice is the way to go. Lifehacker talks about it in this post.
